Intambo ye-Tungsten Eboshiwe Yokwenza Insimbi Yevacuum

Incazelo emfushane:

Izikebhe ze-tungsten, obhasikidi kanye nama-filaments akhiqizwa kusuka ku-tungsten yezinga eliphezulu.Kuzo zonke izinsimbi ezisesimweni esihlanzekile, i-tungsten inephuzu elincibilikayo eliphakeme kakhulu (3422°C / 6192°F), umfutho womhwamuko ophansi kakhulu emazingeni okushisa angaphezu kuka-1650°C (3000°F) futhi inamandla aqine kakhulu okudonsa.I-Tungsten futhi ine-coefficient ephansi kakhulu yokwanda okushisayo kwanoma iyiphi insimbi emsulwa.Le nhlanganisela yezakhiwo yenza i-tungsten ibe into efanelekile yemithombo yokuhwamuka.Ngesikhathi sokuhwamuka, ingaxubana nezinto ezithile ezifana ne-Al noma i-Au.Kulokhu, enye impahla yomthombo wokuhwamuka kufanele isetshenziswe njengezikebhe eziboshwe nge-alumina noma obhasikidi.Ezinye izinto eziwusizo emithonjeni yokuhwamuka yi-molybdenum ne-tantalum.

Iphuzu lokuncibilika eliphezulu kanye nokungagqwala okuphezulu

Impilo ende

Ubumsulwa:99.95% Ubuncane.W

Intambo ye-tungsten eboshiwe isetshenziswa ekwenzeni izakhi ze-heater nezinye izingxenye ze-heater kuma-semicomductou namadivayisi we-vacuum.

Intambo ye-tungsten eboshiwe isetshenziswa njenge-evaporator(isici sokushisa) ku-vacuum metallizing(ukuhwamuka).

Izinhlelo zokusebenza

Ama-Heating Resistors asetshenziswa njengezingxenye zokushisa ukuze acwebe ama-substrates e-kinescope, izibuko, ipulasitiki, insimbi kanye nemihlobiso ehlukahlukene.Izintambo ezigxiliwe zisetshenziswa njengempahla eluhlaza yezinto zokushisa, futhi njengezingxenye zokushisa zama-semiconductors kanye namadivayisi we-vacuum ngokuqondile.
